Yep I have a spare key which works but the buttons are starting to perish. I only have a hawkeye which wont program keys.

Yes , just seen a you tube vid of how to replace it and you basically destroy the old key housing getting the PCB board out and then un-solder and re-solder in a new rechargeable battery then refit it in a new case.

might have to dig the soldering iron out the toolbox.

Mine has 3 buttons below each other with the bottom button being a land rover logo. Its glued together and certainly wouldn't come apart that easy.

My fault. This is my D4 key, but I thought it was the same as when I briefly had a D3. I guess not. Sorry. I must have enjoyed the holiday season too much!

Of course, for anyone who needs to replace a D4 key battery ...

Ean - as mentioned when you unlock the car using the passenger door latch the alarm does go off (as you have found) but as mentioned putting the key in the ignition switches off the alarm and I guess more importantly the immobiliser.

Hi,

So does changing the battery require the key to be reprogrammed? I have a spare key that no longer locks or unlocks. I can have a go changing the battery but I don’t have a tool to reprogram.

Thanks,
Randy

Sorry cant help with that as I have never had an issue. Not sure if programming is lost when power is lost but might be worth while putting the key in the ignition for a while and seeing if the battery will recharge - not sure if the ignition has to be on or not - someone will know but I assume it will on accessory - maybe you could try unlocking the car with your good key and seeing if it will actually start using the flat one and if it does it will definitely be on charge if the battery is capable of retaining its charge.

Thanks, no worries. Yes I’ve tried that, key starts the car but buttons still aren’t working. I’m just guessing it’s the battery not charging.

Thanks anyway.

I just looked at my handbook - it says that the engine cannot be started without the remote control programmed to your vehicle - if you car started with the dud key this indicates that the key is still programmed to your car (maybe the battery is really low but not actually dead) - when the battery in the fob is low a "Key Battery Low" will be displayed in the message centre.

So when you said the key started the car did you then go for a drive to see if it got charged up - the handbook says the engine has to be running to recharge the key.

Unfortunately the handbook only refers you to see the dealer if there are issues such as damage/programming.

Thanks for doing that. Yes I took it for drive for at least an hour. Then tried to lock the car, but no response. I’m thinking of doing a DIY battery replacement, but I am under the impression that as soon as I remove the battery I will lose the programming.

Cheers,
